Sensorfact help clients save an average 10% on energy with Pressac’s energy monitoring sensors

Sensorfact use Pressac’s energy-monitoring sensors to measure the energy consumed by machines at manufacturing facilities. Feeding accurate real-time data into Sensorfact software helps their customers understand, control and reduce energy consumption.

Background

Sensorfact are a software provider based in the Netherlands. They create energy management software for the manufacturing industry, helping businesses understand their energy consumption and the potential to make savings.

While SMEs all want to be more sustainable, and use resources like energy more efficiently, they don’t always have the means to evaluate their consumption and implement better practices. Sensorfact aims to make sustainability simpler and more achievable.

The challenge

Sensorfact started out as energy advisors for manufacturing companies. They’d calculate how much energy each machine used and deliver a report listing energy-saving opportunities and a business case for investment.

However, without any real data on how much energy each machine consumed, their calculations were based on estimates and assumptions. This meant it was hard to show potential customers the true value of what they could offer.

Their challenge was to find a way to accurately measure energy consumption at a machine level. To make it simple and accessible, they wanted a system that could be installed without stopping production and didn’t need a large upfront investment.

The solution

Sensorfact searched for manufacturers of wireless current clamp sensors and found Pressac. Our plug-and-play sensors met their criteria for installation as they simply clip around a phase in a machine or distribution panel. Paying a fixed fee per sensor also helps keep the initial outlay low.

The sensors are wireless, using the EnOcean protocol to send data a distance of up to 50 meters. And because they use energy-harvesting technology they’re incredibly low maintenance, with no need for a power supply or battery.

Sensorfact used a small number of sensors in their own office, then trialled the system with a customer before rolling it out.

The results

Our energy-monitoring sensors measure the amount of energy consumed by each machine every 30 seconds. Data then feeds into Sensorfact’s software, allowing them to give accurate, real-time insights in the energy used by machines and components.

This gives manufacturers greater control over their production process, as they know how each machine is functioning at any time. Continuous energy monitoring allows them to find ways to reduce consumption, such as machines left running after operations have finished and outdated machines causing suboptimal performance. Abnomalies in the machines’ energy pattern are also a key indicator that maintenance or repairs are needed – an advance warning that could prevent breakdowns and unplanned downtime.

On average, these insights have helped Sensorfact’s customers use 10% less energy. Sensorfact have rapidly grown their customer base and their energy-monitoring solution is now used by brands including McDonald’s, Heineken and Schiphol Amsterdam Airport.

“Pressac were great to work with and helped us move quickly – they responded to our queries straight away and were fast to deliver. We also like that they’re open to co-developing new technology with us in the future.”
